In order to give full play to the role of a think tank in technological innovation, accelerate the transformation of innovative technological achievements, realize the connection between industry and technology, better provide innovative technological services for the transformation and upgrading of enterprises in Bao'an District, Shenzhen City and the Guangdong-Hong Kong-Macao Greater Bay Area, and promote the depth of production, education and research. Integration, under the guidance of Shenzhen Bureau of Industry and Information Technology and Bao'an District Bureau of Industry and Information Technology, the Southern Institute of Industrial Technology (hereinafter referred to as "ITRI"), together with Shenzhen Bao'an District Listed Enterprise Association and Satellite Internet of Things Industry Association, in 2022 On the afternoon of June 30, 2009, the third technical salon was successfully held in the salon activity center of ITRI.

The third technical salon event invited the Executive Director of Taizhou Research Institute of Southern University of Science and Technology, a member of the Special Committee of the Chinese Society of Automation, an evaluation expert of Shenzhen Development and Reform Commission, Assistant to the Dean of the Robot Research Institute of Southern University of Science and Technology, and Professor Liu Wei of the Department of Mechanical and Energy Engineering. Sharing the theme of "3D Vision Inspection Robot Technology and Application for High-end Manufacturing". At the same time, Xinwangda Electronics Co., Ltd., Inspur Group Scientific Research Institute, Shenzhen Jinlong Technology Co., Ltd., Shenzhen Hengyido Wonderful Technology Co., Ltd., Weizhi Optoelectronics (Shenzhen) Co., Ltd., Shenzhen Baolian Artificial Intelligence Technology Co., Ltd. Co., Ltd., Shenzhen Purdue Technology Co., Ltd., Shenzhen Zhiqinglan Technology Co., Ltd., Guangzhou Core Artificial Intelligence Technology Co., Ltd. and other business leaders and related technical leaders, a total of more than 30 people participated in this event online or offline. Activity.

First, Professor Sun Dazhi, Vice President of ITRI, delivered a speech for the event, and introduced the overall development of ITRI in detail from three aspects: unit situation, strategic layout and cooperation model.

Then, Professor Liu Wei shared the theme of "3D Vision Inspection Robot Technology and Application for High-end Manufacturing". Professor Liu Wei first briefly introduced the development history and achievements of SUSTech and the Department of Mechanical and Energy Engineering. Compared with the research directions of mechanical majors in the world's top universities such as MIT, Stanford, Berkeley, etc., the Department of Mechanical and Energy Engineering of SUSTech focuses more on the "new" research fields of "new machinery": intelligent manufacturing, forming manufacturing and 3D printing, Extreme manufacturing (precision machining), robotics and automation and energy engineering.

Then, Professor Liu Wei made a rich presentation from multiple dimensions, including the future development of intelligent manufacturing, the advantages of machine vision as the eye of intelligent manufacturing, the current development pain points of the machine vision industry, the core technical advantages and industrial applications of the project team in the field of machine vision, etc. great speech.

The "14th Five-Year Plan" clearly pointed out that the in-depth implementation of intelligent manufacturing and high-end manufacturing will enable key enterprises in key industries to initially achieve intelligent transformation by 2025; by 2035, key enterprises will basically achieve intelligent transformation. Among them, quality inspection is an essential and important part of high-end manufacturing. ReportLinker released a report showing that the "global test and measurement equipment industry" is close to $35 billion, of which dimensional measurement exceeds 80%; at the same time, according to Grand View Research, the 3D machine vision market size will reach $24.8 billion in 2027, with a compound annual growth rate close to 15%.

In the era of Industry 4.0 intelligence, that is, the era of using information technology to promote industrial transformation, machine vision is the eye of intelligent manufacturing. Machine vision equipment is a device that obtains the characteristic image of the detected object with the help of optical devices and non-contact sensors, and extracts information from the image through a computer, analyzes it, and then realizes detection and control. Machine vision capabilities include visual positioning, pattern recognition, dimensional measurement, and defect detection. As an extension of human vision, machine vision has multiple advantages such as high accuracy, fast speed, low cost, and easy information integration. It can replace manual high-intensity continuous and accurate operations in various production environments, greatly improving work efficiency and quality.

However, there are still many pain points in the development of the machine vision industry, which are mainly reflected in the following four aspects:

(1) Miscellaneous, that is, the object structure is complex and diverse, requiring multi-camera and multi-view motion detection;

(2) Expensive, that is, the hardware cost of 3D industrial cameras and moving parts is high, and they can only take pictures without functions;

(3) Difficulty, that is, it is very difficult for the customer's factory to switch production lines in the later stage, and the investment in time cost, labor cost, and material resources is huge, and the efficiency is not high

(4) Complex, that is, the equipment manufacturers are cumbersome to maintain in the later stage, and the personnel investment is large.

Professor Liu Wei introduced the core technologies of the project team in detail from the perspectives of binocular vision technology, time-of-flight (TOF) vision technology, 3D structured light vision technology and confocal vision technology: (1) Optoelectronic integration of precision optical design industrial vision "probes" with multiple varieties and serialization; (2) next-generation ultra-high-speed industrial bus and FGPA ultra-high-speed interface protocol, the accuracy covers 1mm, 0.1mm, 0.01mm, 0.001mm; (3) artificial intelligence And the core algorithm engine of industrial software, including probe signal to 2D/3D signal recovery, multi-probe and multi-view intelligent splicing; functional algorithm integration, um-level defect identification, detection and positioning; .dwg/.stp drawing model analysis, no need for manual labor Code drawing engine, digital twin.

At the same time, combined with the actual project cases that have been delivered, Professor Liu Wei focused on sharing the project as a key link in Tesla's supply chain, the best in the online 3D position detection and online 3D flatness detection of automotive heat exchanger parts In practice, and as a supplier of global 5G communication main equipment manufacturers, customized output of 5G communication module 3D coplanarity testing equipment, etc. In the actual delivery process of the above major projects, a new mode of precision measurement in industrial vision has been truly achieved, that is, "eye-brain integration".

Finally, Professor Liu Wei answered the practical problems encountered in the current production and manufacturing environment raised by the representatives of various enterprises participating in the technical salon activities, and conducted a more in-depth exchange and discussion, saying that the follow-up will rely on the industry The research institute platform continues to strengthen cooperation and exchanges with related enterprises, and accelerate the transformation of innovative technologies.

Next, ITRI plans to hold the fourth technical salon event again in mid-July, to continue to provide an exchange and interaction platform for the deep integration of innovative technologies and industries, and to provide services for the transformation and upgrading of enterprises in Bao'an District, Shenzhen City and the Guangdong-Hong Kong-Macao Greater Bay Area. Innovative technical services to promote the deep integration and development of production, education and research.
